US 6,640,302 B1 · Secure intranet access

Abstract

Methods, signals, devices, and systems are provided for secure access to a network from an external client. Requests for access to confidential data may be redirected from a target server to a border server, after which a secure sockets layer connection between the border server and the external client carries user authentication information. After the user is authenticated to the network, requests may be redirected back to the original target server. Web pages sent from the target server to the external client are scanned for non-secure URLs such as those containing “http://” and modified to make them secure. The target server and the border server utilize various combinations of secure and non-secure caches. Although tunneling may be used, the extensive configuration management burdens imposed by virtual private networks are not required.

Dependent claims

A border server comprising:

secure connection software for secure communication with a client computer, said client computer located within an insecure network;
insecure connection software for communication with a target server, said target server located within a secure network;
and
a uniform resource locator transformer to transform secure requests received from said client computer to insecure communication requests to send to said target computer within said secure network, said uniform resource locator transformer also transforming insecure data received from said target server into secure communication, within said secure network, for sending to said client computer, and wherein the transforming of the secure requests occurs while the client computer is authenticated.
